All My Ancestry Results

Below is a snapshot of the information you will receive with the results of your All My Ancestry test.

Chromosome Painting

You inherit one copy of each pair of chromosomes 1 to 22 from your mother and one from your father. These account for about 95% of your DNA. If you have relatively recent mixed ancestry you will be carrying blocks of DNA from different continents.

For example if your mother was British and your father Nigerian, then one copy of each chromosome will be African in origin and one copy European.

If the mixed ancestry is further back in time, e.g. if one grandfather was European, with three grandparents SE Asian, then about half of the blocks on one copy of each chromosome will be East Asian, the rest being European.

As we go further back, the total length of DNA from the mixture decreases until eventually after 8 or more generations it can be gone entirely. Although your parents inherit half their DNA from your grandparents, because it is random which of their copies you inherit at any given place along the chromosomes, you can by chance get more DNA from one grandparent than from another. Over the generations this effect means that eventually you have pedigree ancestors who contributed no DNA to you, conversely other pedigree ancestors contributed more than would be predicted by chance. Hence the proportion of DNA from different ancestries can be very variable, and differs among siblings for example.

The graphic shows the two copies of each chromosome, from the largest chromosome (1) at the top to the smaller ones at the bottom. These are coloured according to the inferred ancestry of the segments of chromosome – shown in the map.

How does it work? We first use a statistical model to separate the DNA markers you inherited from your mother and father. These then undergo a principal components-based analysis in a sliding window across the chromosomes, followed by a smoothing procedure.

Global Connections Plot

The plot is a summary of your genetic relationships using markers from across your genome – it shows the average geographical origin of all your ancestors.

This is done by comparison to thousands of samples of known ancestry from around the world. Each sample is represented by a small card and the closer together they are the more closely related they are. The population of origin is written on the card and they are coloured according to their continent or region of origin.

People within one population tend to be more closely related to one another than to people in other populations. In the global plot the different major continents and regions also group together and merge into one another: Africa, West Asia, Europe, South Asia, East Asia, the Pacific and Native America. People of mixed heritage are also included and you can see they plot between their parental populations.

Population Percentage

We have used a statistical model of genetic ancestry to infer what proportions (%) of your genome come from 8 different regions of Europe. The colourful chart shows these percentages for over 800 reference individuals: each person is represented by a very thin vertical line which is coloured according to the percentage of their genome estimated to be ancestrally Finnish, Ashkenazi Jewish, Anatolian-Caucasian, Steppe Turkic, Balto-Slavic, Northwest European, Mediterranean or Basque-Iberian. You will be able to zoom in on yourself so that you can see the bar more clearly.

How does it work? A model-based approach is used to estimate individual ancestry using maximum likelihood. The reference populations are included in the modelling but no structure is imposed, the model finds the seven most differentiated clusters in the data without using population labels.
